Kenya building collapse: Demolition of unfit houses starts

Authorities in Kenya's capital Nairobi have begun demolishing homes in an area where the collapse of a building killed at least 42 people last week.

Eight buildings deemed unfit to live in were the first to be destroyed in the district of Huruma. More than 200 are to follow.
Officials say many of the houses are substandard or built on unsafe grounds.
A recue operation continues at the collapsed building, which had been declared unfit for human habitation.
At least 70 people are still missing, while 140 have been rescued.
